1. Park the vehicle on a level surface, shut down
the engine and set the parking brake. Chock the
tires.
2. Check the I-bolt torque. See
Table 2 for I-bolt
torque specifications. Tighten in a diagonal pat-
tern as shown in
Fig. 9 and Fig. 10. Set a click-
type torque wrench to the mid-point value for the
fastener being checked. Turn the wrench in a
clockwise motion (looking up) until the torque
wrench clicks, then release pressure on the
torque wrench, and turn the torque wrench again
until it clicks. If the bolt turns on the second
application, the bolt is stretching and must be
replaced.
